Description

Technical Field

[0001] The utility model belongs to the technical field of educational equipment, and in particular relates to a traffic safety teaching aid. Background Art

[0002] Traffic safety teaching aids are educational tools primarily used by primary and secondary school students. Existing traffic safety teaching aids primarily rely on single audio playback, lacking a practical display device. Furthermore, there are no devices or equipment that can provide customized audio instructions based on pedestrians' positions and behaviors. Improving the real-life effects of traffic safety teaching aids has been a topic of research for those skilled in the art.

[0003] Chinese utility model patent No. 201620428970.6 discloses an intelligent traffic demonstration teaching aid model, which includes a teaching aid body, the upper portion of which is connected to a handle, a camera mounted on the top of the teaching aid body, a road surface on one side of the camera, a guide rail within the road surface, a test vehicle mounted on the guide rail, a baffle at one end of the test vehicle, an infrared receiver within the baffle, a control chip mounted on one side of the infrared receiver, traffic lights on both sides of the road surface, and an infrared transmitter on one side of a pedestrian crossing. This intelligent traffic demonstration teaching aid model primarily simulates a car driving scene and does not provide safety warnings for pedestrians. Utility Model Content

[0004] The utility model provides a traffic safety teaching aid with a simple structure, good real-scene education demonstration effect and sensitive response.

[0005] A traffic safety teaching aid includes a mounting plate. A pedestrian safety waiting area, a motor vehicle driving area, a sidewalk, and a traffic light pole are mounted on the front of the mounting plate. The traffic light pole is equipped with an indicator light. A circuit control board is mounted on the back of the mounting plate. The circuit control board includes a control circuit that senses the position and movement of a simulated human figure. A magnet is mounted on the bottom of the human figure. The magnet controls a sensing switch in the control circuit, which triggers a speaker in the control circuit to emit voice information about the area where the human figure is located. This traffic safety teaching aid, by mounting a pedestrian safety waiting area, a motor vehicle driving area, a sidewalk, and indicator lights on the front of the mounting plate, emits voice information about different areas in conjunction with the position and movement of the human figure. This provides a real-world scenario-based traffic safety education program, enhancing the effectiveness of warning education.

[0006] The mounting plate is a square structure with fence panels around it. Pedestrian safety waiting areas are set at the four corners of the mounting plate. Motor vehicle driving areas, sidewalks and indicator lights installed on traffic light poles are set between two adjacent pedestrian safety waiting areas, increasing the sensing area to better adapt to real and complex traffic environments.

[0007] The inductive switch is a reed switch. When the magnet at the bottom of the simulated person approaches the reed switch and the magnetic force of the magnet exceeds the elastic force of the reed of the reed switch, the two reeds will attract and conduct the circuit to play the voice in the corresponding position area.

[0008] The control circuit includes a control chip, which is connected to a first pin connector, a second pin connector, a third pin connector, a digital-to-analog converter, and an indicator light control circuit. The digital-to-analog converter circuit is connected to a speaker. The indicator light control circuit includes a first light-emitting transistor, a second light-emitting transistor, and a third light-emitting transistor, each of which is independently connected to an independent third pin connector. Each third pin connector is connected to a sensing circuit formed by two or more sensing switches connected in parallel. The first light-emitting transistor is red, representing a red light; the second light-emitting transistor is green, representing a green light; and the third light-emitting transistor is yellow, representing an amber light.

[0009] The utility model enables students to have a deeper understanding of the working principle of traffic lights and improves students' safety awareness through the installation and use of traffic safety teaching aids. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is combined with Figure 1-4 The specific implementation method further describes the technical solution of this patent in detail.

[0016] A traffic safety teaching aid includes a mounting plate 1. The front of the mounting plate 1 is equipped with a pedestrian safety waiting area 4, a motor vehicle driving area 5, a sidewalk 6, and a traffic light pole 3. The traffic light pole is equipped with an indicator light 2. The back of the mounting plate 1 is equipped with a circuit control board 8. The circuit control board 8 is provided with a control circuit. The control circuit senses the position and movement position of a simulated person. A magnet is provided at the bottom of the simulated person. The magnet controls an induction switch 19 in the control circuit. The induction switch 19 triggers a speaker 14 in the control circuit to emit voice information about the area where the simulated person is located.

[0017] In order to increase the environmental consistency between the sensing area and the traffic scene, the mounting plate 1 is a square structure with fence panels 7 around it. Pedestrian safety waiting areas 4 are provided at the four corners of the mounting plate 1. Between two adjacent pedestrian safety waiting areas 4, there are motor vehicle driving areas 5, sidewalks 6 and indicator lights 2 installed on traffic light poles.

[0018] In order to improve the sensing sensitivity, the sensing switch 19 is a reed switch 9 , the number of the reed switches 9 is more than two, and a single set of sensing circuits is connected in parallel.

[0019] The preferred control circuit includes a control chip 12, which is connected to the first pin connector 11, the second pin connector 10, the third pin connector 18, the digital-to-analog converter 13, and the indicator light control circuit. The digital-to-analog converter 13 is connected to the speaker 14. The indicator light control circuit includes a first light-emitting transistor 16, a second light-emitting transistor 15, and a third light-emitting transistor 17, each of which is independently connected to an independent third pin connector 18. Each third pin connector 18 is connected to a sensing circuit formed by two or more parallel inductive switches 19. The first light-emitting transistor 16 is red, the second light-emitting transistor 15 is green, and the third light-emitting transistor 17 is yellow.

[0020] The traffic lights in the utility model adopt timing control. Traffic lights are set at traffic intersections. When the simulated person stops at or passes through the pedestrian safety waiting area, motor vehicle driving area, and sidewalk area, the induction switch sends a signal to the control chip, and the control chip sends a voice to allow or prohibit passage according to the status of the traffic lights in the area at that time.

[0021] For example, when a simulator stands in a pedestrian safety waiting area, a voice message "waiting for the red light" is played. If the simulator passes through the pedestrian area when the light is red, a red light violation alarm is issued. If the light is green at this time, the control chip sends a voice message allowing the simulator to pass through.

[0022] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
